Tkinter Label widgets are used to add text or images to the application. We can even configure the basic properties of labels using the config(options) method. Generally, in order to configure the widgets property dynamically, we use callback functions where we modify the value of attributes.
In this example, we will modify the color Tkinter Labels by defining the callback function. The function can be activated by a button that forces the labels to change the color.
#Import required libraries from tkinter import * from tkinter import ttk #Create an instance of tkinter frame win= Tk() #Define the geometry of the window win.geometry("750x250") #Define a function to Change the color of the label widget def change_color(): label.config(bg= "gray51", fg= "white") #Create a label label= Label(win, text= "Hey There! How are you?", font= ('Helvetica20 italic')) label.pack(pady=30) #Create a Button ttk.Button(win, text="Change Color", command=change_color).pack(pady=20) win.mainloop()
Running the above code will display a window that contains a label and a button.
Now, click "Change Color" button to change the color of the Label widget.
